Chitetezo cha ma Surge pamagetsi onse amagetsi ndi ma siginecha ndi njira yotsika mtengo yopulumutsira nthawi yocheperako, kuonjezera dongosolo ndi kudalirika kwa data, ndikuchotsa kuwonongeka kwa zida zomwe zimachitika chifukwa chanthawi yochepa komanso ma surges.Itha kugwiritsidwa ntchito pamtundu uliwonse wa malo kapena katundu (1000 volts ndi pansipa).Izi ndi zitsanzo zamagwiritsidwe ntchito a SPD m'mafakitale, malonda, ndi nyumba zogona:

Makabati owongolera, owongolera malingaliro osinthika, owongolera ma mota amagetsi, kuyang'anira zida, mabwalo owunikira, metering, zida zamankhwala, katundu wovuta, mphamvu zosunga zobwezeretsera, UPS, ndi zida za HVAC zonse ndi zitsanzo za kugawa mphamvu.

Madera olumikizirana, matelefoni kapena ma fax, ma feed a TV, makina achitetezo, ma alamu owonetsera ma alarm, malo osangalalira kapena zida za stereo, khitchini kapena zida zapanyumba.

Ma SPD amatanthauzidwa motere ndi ANSI/UL 1449:

Mtundu 1: Wolumikizidwa kwamuyaya, wopangidwa kuti alumikizane ndi gawo lachiwiri la chosinthira chautumiki kumbali ya mzere wautumiki kulumikiza chipangizo chopitilira muyeso (zida zothandizira).Ntchito yawo yayikulu ndikuteteza kuchuluka kwa magetsi amagetsi kumayendedwe akunja omwe amachititsidwa ndi mphezi kapena kusintha kwa banki ya capacitor.
Mtundu wa 2: Wolumikizidwa kwamuyaya ku mbali yonyamula katundu chotsani chipangizo chowonjezera (zida zothandizira), kuphatikiza malo amtundu wamtundu.Cholinga chachikulu cha oteteza maopaleshoniwa ndikuteteza zida zamagetsi ndi zotengera zotengera ma microprocessor ku mphamvu yotsalira ya mphezi, ma surges opangidwa ndi ma mota, ndi zochitika zina zopangira opaleshoni mkati.

Mtundu wa 3: At-the-Point-Of-Use Kuchokera pagawo lamagetsi opangira magetsi mpaka kugwiritsidwa ntchito, ma SPD ayenera kumangidwa ndi utali wa conductor wa 10 mita (30 mapazi).Ma SPD omwe ali ndi zingwe, pulagi yolunjika, ndi mtundu wa cholandirira ndi zitsanzo.

Type 4: SPD (Component Recognized) Component Assembly -- Misonkhano yachigawoyi imapangidwa ndi gawo limodzi kapena zingapo zamtundu wa 5 SPD, komanso cholumikizira (mkati kapena kunja) kapena njira yodutsa UL 1449, Gawo 39.4 lapano mayesero.Awa ndi misonkhano ya SPD yosamalizidwa yomwe nthawi zambiri imayikidwa muzinthu zogwiritsidwa ntchito kumapeto ngati zovomerezeka zonse zakwaniritsidwa.Misonkhano yachigawo cha Type 4 iyi siyiloledwa kuyikidwa m'munda ngati SPD yokhayokha chifukwa siyikwanira ngati SPD ndipo imafuna kuwunikanso.Kutetezedwa kopitilira muyeso kumafunika pafupipafupi pazida izi.

Type 5 SPD (Component Recognized) - Zida zodzitchinjiriza zodzitchinjiriza, monga ma MOV, zomwe zitha kuyikidwa pa bolodi losindikizidwa ndikulumikizidwa ndi mayendedwe awo, kapena zomwe zitha kusungidwa m'malo otchingidwa ndi kuyimitsidwa ndi waya.Zigawo za Type 5 SPD izi sizokwanira ngati SPD ndipo ziyenera kuwunikiridwa patsogolo musanayike m'munda.Type 5 SPDs nthawi zambiri amagwiritsidwa ntchito popanga ndi kumanga ma SPD athunthu kapena misonkhano ya SPD.
